Hamas is getting exactly what it wants...a full-scale invasion of Gaza, with massive civilian casualties. That invasion will accomplish...nothing. But it'll score big big big diplomatic points for Hamas. Probably will force the Saudis away from any peace accords with Israel.
And of course...the warhawks over here are screaming, spittle flying, for a full-scale war--against somebody. Maybe Hamas. Maybe Iran. Maybe Iceland. Doesn't matter as long as there are lotsa big booms. The doves who didn't want to send aid to Ukraine are now full-blown screaming hawks. That's also what Hamas wants.
I wonder if the various Lindsay Grahams and other chest-thumping RepubliQ warhawk yahoos even realize that they're being perfect Hamas puppets.
This also helps to prop up Netanyahu and what was an alarmingly antidemocratic government. In fact, their Supreme Court debacle reminds me of ours, with the Trump-packing that turned it into a laughingstock. Whatever was going to happen to Netanyahu, with all the legal trouble he's in (remind you of anybody?), is going to be put on hold while Israeli troops are in Gaza.
The immoral aspect of all this is that the poor bastards in Gaza who are ruled by Hamas weren't responsible for the attacks, but they're the ones getting blown up. Israel says it's going after "Hamas targets," but what does that even mean when the target is an apartment block where 200 people live?
I don't pretend to have an answer to the whole mess. But it's clear that unless they want to commit genocide, Israel can't solve this problem with brute military force.
